- Denoting a spatial arrangement of structures that subserve various frequencies, as in the auditory pathway. [tono- + G. topos, place]
* * *to·no·top·ic .tō-nə-'täp-ik adj relating to or being the anatomic organization by which specific sound frequencies are received by specific receptors in the inner ear with nerve impulses traveling along selected pathways to specific sites in the brain
* * *tono·top·ic (ton″o-topґik) having a spatial arrangement such that certain tone frequencies are transmitted along a particular portion of the structure, as in the cochlear nuclei.
